Two types of seismic calucation methods that are response spectrum analysis and time - history analysis are used to analyze the seismic response of kiewitt ' s suspen - dome under lateral seismic action and vertical seismic action . the result obtained by above - mentioned methods and the code method are compared . genetic algorithm method is proposed to optimize the prestress of suspen - dome 本文采用振型分解反应谱法和时程分析法两种方法，对kiewitt型弦支穹顶预应力结构的水平和竖向地震作用下的地震效应进行计算分析，并同现行的规范和规程的规定方法一10重力荷载代表值简化法计算结果进行了比较分析。
